4.0 Performance Parameter
4.1 Resistance(R90)
requirement:R90＝1.084KΩ±1%
test method:90℃±0.1℃.(90℃±0.1℃ in the oil.)
4.2Thermal time Constant(τ)
requirement:τMax15s, τMax18s
test method:In the water, When the products be put into the water at 25℃ from the water at 50℃, Thermal time constant is the time that cost by the resistance becoming to be the value at34.2℃.
4.3Dissipation Constant(δ)
requirement:3mw/℃,3mW/℃(min, in air)
test method(The product will be join with the following circuit at 25±0.5℃ in still air.
4.4 Max.rated power
requirement:P≈275mw
calculating method:P≈δ×(80℃－25℃)
80℃ is the maximum temperature that the product is heat by itself.
4.5Insulation resistance

6.0 Method of the stockpile
6.1 The height of stacks products cannot overbalance four boxes,in the stackpile and the course of transport.
6.2 The packing products of inside must placed desiccant.Allowance used the angone way to transport,but must prevent therain and the snow direct or indirect shower bath and damnification of these products.
6.3 The products are stockpiles candition of the tencperature is about -10℃/+40℃,the opposite humidity not bigger too 80%,acidic and alkalescent of substance,erode gas or radiant point are not should enclose the products.
